BEDMATTRESS.

Specification of Letters Patent.

Patented Har. 15, 1921.

Application filed September 8, 1919. Serial No. 322,511.

To all 'whom it may concern:

Be it known that I, BERNARD IVIGIESE, a

citizen of the United States, and a resident of the city of Chicago,county of Cook, and State of Illinois, have invented certain new anduseful Improvements in lied-Mattresses, of which the following is aspecification.

My invention relates to improvements in bed mattresses, and has for itsobject the provision of an improved construction of this vcharacterwhich is durable and efficient in use.

Other objects will appear hereinafter.

. The invention consistsin the combinations and arrangements of partshereinafter described and claimed.

The invention will be best understood by reference to the accompanyingdrawings forming a part of this specification, and in which,

Figure l is a perspective view of the outer portion of a mattressembodying the invention.

Fig. 2 is a similar view tion of the mattress.

Fig. 3 is a partial transverse section of the mattress assembled, saidsection being taken on line 3 3 of Fig. 4.

Fig. 4 isa top plan view of the assembled mattress with portions broke-naway at one corner, and shown in horizontal section.

The preferred form of construction, as illustrated in the drawings,comprises an outer integral box spring mattress construction made inrectangular form with a central recess. Said mattress portion consistsof a suitable rectangular frame 5, preferably of wood and having a topcushion 6, supported by means of spiral springs 7 on the top 8 of frame5, as shown'. The frame 5 is provided at its bottom with transverseslats 9 passing across the center opening or recess in said frame, andan inner mattress section isremovably fitted within said recess, restingupon said slats. The inner mattress Consists of a suitable Wooden frame10 having a cushion top 1l supported by spiral springs 12, as indicated,said springs resting at the bottom on slats 9 extending across the framel0, as shown. As indicated, the

of the inner por- .springs 7 are considerably shorter than springs l2and are considerably stiffer, so that the outer portion 6 of themattress will be less yielding thanthe inner portion 11 thereof, andwhereby the outer portion of the mattress is better adapted to resistthe weight of a person sitting thereon, when the weight is concentratedin a smaller area.

By this arrangement the position of the center mattress portion may beshifted occasionally, thus shifting the points or portions bearing thegreatest weight or strain, and thus greatly prolonging the life of themattress and preventing sagging of the inner portion thereof.

lVhile I have illustrated and described the preferred form ofconstruction for carrying my invention into effect, this is capable ofvariation and modification without departing from the spirit of theinvention. I, therefore, do not wish to be limited to .the precisedetails of the construction set forth. but desire to'avail myself ofsuch variations and modifications as come within the scope of theappended claims.

Having described my invention, what I claim as new and desire to secureby Letters Patent, is 1. A bed mattress comprisingA an outer in tegralmattress vconstruction constituting a continuous, unbroken. border ofthe mattress and having a central recess therein; supporting slatstransverse the bottom ofsaid recess; and an inner mattress constructionremovably fitted within said recess and resting upon said supportingslats, substantially as described.

2. A bed mattress comprising an outer integral mattress constructionconstituting a continuous, unbroken border of the mattress and having acentral recess therein; supporting slats transverse the bottom of saidrecess; and an inner mattress construction removably fitted within saidrecess and resting upon said supporting slats, the outer mattressconstruction being less yielding than the inner mattress construction,substantially as described.

Iny testimony whereof I have signed myv name to this'specification inthe presence of two subscribing witnesses.
